The study of observed species of Anchusa L. genus (Boraginaceae) in ruderal and segetal environments of Hamedan city (west of Iran)

During 2009-2011 some of the ruderal and segetal areas inside of Hamedan city and its suburb (to 30 km of Hamedan) involving some of the farms, gardens, green spaces, waste lands and also margin of terrafic regions (streets and superhighways) were compared based on ecological-floristical view in relation to presence and dispersal of Anchusa L. genus. Two species and one sub species from this genus already have been observed and collected from studied areas, Anchusa italica Retz. (with two varieties, A. italica var. italica and A. italica var. kurdica) and Anchusa strigosa Labill. species and Anchusa arvensis (L.) Bieb. subsp. orientalis (L.) Nordth.sub species. The most dispersal belongs to A. italica with its two varieties in environments with H3 (β-euhemerob) and H4 (α-euhemerobe) hemeroby degrees. A. arvensis subsp. orientalis was mostly observed in agricultural areas, with relatively a few numbers, in two blue and white colors. A. strigosa species with H3 (β-euhemerob) hemeroby degree, was observed with highly limited dispersal only in one region, outside of the city.
